Sagot :

Answer:

a = 45 degrees

Explanation:

A flat line is 180 degrees, the given angle is 90 degrees
90 = half 180
so 2a = 90
90 / 2 = 45
a = 45 degrees

Answer: 45°

Explanation:

     A straight line is equal to 180°. Since the angle is made up of 90° and two a angles, we will subtract 90 and divide by two.

180° - 90° = 90°

90° / 2 = 45°

     a = 45°
